 MC3479PGonsemi | L293DNETexas Instruments | |
|---|---|---|
| FFF Compatibility | The pin assignments are completely different and require a full PCB layout redesign.Both devices are housed in a standard 16-PDIP package (through-hole) with identical lead pitch and row spacing.L293DNE can drive the same bipolar stepper motor, but lacks the built-in step decoding/sequencing logic (no Clock or CW/CCW pin). The phase sequencing must be handled by an external microcontroller or an indexing IC. Additionally, it requires separate VCC1 (logic) and VCC2 (driver) power supplies, whereas the MC3479PG operates from a single supply. | |
 AI Summary | MC3479PG by onsemi: Bipolar Motor Driver CMOS Parallel 16-PDIP. | The L293DNE is a widely available 16-PDIP quadruple half-H-bridge driver with internal clamp diodes. It can drive a bipolar stepper motor but requires external logic to generate the step phases because it does not include a built-in translator like the obsolete MC3479PG.

You searched one part. Parter watches your whole BOM.
All your BOM, at once
Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.
Hear about problems before they hit production
Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.
Qualified replacements in minutes, not days
Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
